Do a fastlane search on self leveling parts: 2 accumulators, 1 controller and 2 struts. Add in the labor.

If you're really interested in a wagon, allow me to suggest the 124 e320 (rear wheel drive). I've driven mine with snow tires and felt very confident with it in northern PA & NJ. Your winters are milder than here and if you would get caught in a blizzard in the Appalachian Mountains the heater will keep you warm.
